Reverse Dieting After Cutting

The end of a cut is a fork in the road. You have spent weeks in a deficit, your maintenance has quietly drifted down, and you are eating fewer calories than your recovered body would burn. Snap straight into a big bulking surplus from there and a good share of the extra tends to arrive as fat, because your metabolism has not yet climbed back up. A reverse diet uses this window deliberately: it raises your intake in small weekly steps so your maintenance recovers first, then a lean bulk begins from that higher, honest starting point. For a physique athlete coming off a show or a lifter ending a summer cut, this is the difference between a clean lean gain and a rebound. The tool above defaults to a building protein target and a moderate pace because that is the typical post-cut setup, and you can tune both.

For lean, muscular bodies, protein set from scale weight can overshoot, because a chunk of that weight is not the tissue protein serves. If you know your body fat percentage, the tool doses protein off lean mass instead — the muscle, bone and organs that actually drive your protein need. Enter it in the optional field and the maths shifts from bodyweight to lean tissue automatically. Not sure of your body fat or lean mass? Estimate them first with the Lean Body Mass Calculator, then bring the figure back here so the protein target reflects your composition rather than the number on the scale.

Take a lean male, 30 years old, weighing 82 kg at 180 cm, moderately active, at 12% body fat. His resting burn is about 1,800 calories, and multiplied by his activity that gives a maintenance near 2,790 a day. At 12% body fat his lean mass is roughly 72 kg, and a building protein target of about 2.4 grams per kilogram of that lean mass puts him near 173 grams of protein a day. If he finished his cut eating 2,200, the gap to maintenance is 590 calories, which at 100 a week closes in about six weeks. Protein stays fixed at 173 throughout while the weekly rise flows mostly into carbohydrate — the fuel that refills glycogen and powers his training back up. Once he is at maintenance, splitting those calories with the Macro Calculator sets the plate for a lean bulk. For the full schedule and rebound-risk read, the Reverse Dieting Calculator is the parent tool this page is built from.

Keep Lifting So the Surplus Builds Muscle

The added calories only turn into muscle if you give the body a reason to build it. Keep resistance training in your week through the whole reverse, chasing progressive overload as your energy and glycogen return. Paired with high protein, that is what biases the small surplus toward lean tissue rather than fat. Skip the training and the extra food has nowhere useful to go. Judge the ramp on a one-to-two-week weight trend, and if the scale climbs faster than about half a percent of bodyweight a week, hold the current calories before the next step.
